I've realized a small desktop application for displaying maps and adds some landmarks on them.
It uses the code that can be downloaded "here":http://qt-project.org/quarterly/view/location_and_mapping_services .
To menage the map, I use a QGeographicsGeoMap object. I want to have a cache for using my program also without an internet access. Is it possible? How?
At the moment the Qtmobility doesn't provide cache service.
The Marble API, at this "link" :http://marble.kde.org/ provides offline caching service.
